Mine seems to be doing the same thing. Fan running pretty constantly with not a lot going on. I went ahead and did the items that you suggested: [sean@homebox ~]$ grep MHz /proc/cpuinfo model name : Intel(R) Pentium(R) M processor 1600MHz cpu MHz : 599.542 Also, my /etc/cpuspeed.conf: VMAJOR=1 VMINOR=1 # uncomment this and set to the name of your CPUFreq module #DRIVER="powernow-k7" # Let background (nice) processes speed up the cpu OPTS="$OPTS -n" # Add your favorite options here #OPTS="$OPTS -s 0 -i 10 -r" # uncomment and modify this to check the state of the AC adapter #OPTS="$OPTS -a /proc/acpi/ac_adapter/*/state" # uncomment and modify this to check the system temperature #OPTS="$OPTS -t /proc/acpi/thermal_zone/*/temperature 75" Since I have no idea what I am doing either, should any of this be modified? I didn't see anything like this in FC3, so it must be some kind of change in FC4. Sean
